what you are seeing is an htc desire in which I'm playing a little game

it is not finished, it is like an alfa version that I have made by myself.

In the next tutorials we are going to learn game programming concepts,

android specific characteristics for game programing

and a little of game achitecture "How we are going to structure a game"

Here we have the same game but with less characters or guys

ok, as you can see here are bad and good guys

when you kill one of these they scream as a terrified woman and leave a blood stain,

it makes an "auch" and leaves a blood stain too

after a few seconds the blood stain disappears

try not to kill to the good guys. In other words, kill the boys and not the girls

here I present you a summary of what we are going to see in the next tutorials.

what you really see is a picture painted over another

a computer monitor can print 80 pictures per second

in this simple game we are making we are going to print

10 frames per second, that means we are going to print 10 pictures in a second

this is printed so many time per second that we see a video animation

also in this game loop ... in adition to updating the picture

these are the 2 principal methods called by the game loop

in the update each character is updated. The position, ...

if it reached the border, to turn and go in the opossite direction

it updates what people call "the game physics" for example

when a character walks it has an inertia,

calling this update, in each call we move the character.

3. Sprites: is an old concept, it is the concept of...

the sprites normally have characteristics like movement

they can have sound, ... they are like a little entity

then... this is a sprite, will see it later on...

Collision detection: it is when it is necessary to now when ... for example this one gets to the border here

and goes in this direction. It is detected that it was going to get out from the screen

and when it detects the border it changes direction

when I click, how does it know if I kill some one? It needs to be aware ...

that in the x, y position where I click there was a guy

and then when it detects that here there is a collision between the click position and a guy I make the character disappear and

the blood stain appears, after a few seconds it disappears too

Game resources: ... how to find the images

we are going to see this in detail but for now .... let's go here to resource

here we have another bad one, you can see it is walking front, the legs are in different positions

here we have a good one. I made this with a program ...

I saw in a web that we are going to see in the next tutorials.

see, here it is going left moving it's legs

I don't know if you are going to hear this, but when you click here

this is the scream of a woman and this is when we click on the man

we are going to see Android specific characteristics used for the game. For example the use of SurfaceView
